I need help from the [math geniuses]… dB's, amplitudes, meter-displays…

The attached patch shows a live.meter~ displaying a value (fed to the sig~ above it.
Next to the meter~ is a slider of equal height, giving a range of 0. to 1.
When moving the slider to the same height as the live.meter~ level display I’d like for the slider to give the same value as whatever the float is feeding to the sig~. Hard to explain but it’s all in the patch. Basically, I’m missing some math applied to the output of the slider.

I appreciate your help, greatly, as always.

Best,

antwan
